Sclerotomy for pars plana vitrectomy PETER LEAVER AND DAVID McLEOD From the Vitreous Clinic, Moorfields Eye Hospital, London
SUMMARY
A sclerotomv technique for vitreous
Closed vitrectomy has largely supplanted the 'open sky' method, particularly because it results in minimal interference with the integrity of the globe. Ideally the pars plana sclerotomy should be sufficiently watertight to allow the intraocular pressure to be maintained during surgery without impeding free movement of the vitrectomy instrument within the eye. We describe a sclerotomy technique for use with the Machemer VISC, Douvas Rotoextractor, and Peyman Vitrophage which achieves these objectives. Method A limbus-parallel incision 4 mm in length is made through half the thickness of the sclera 40 to 5-0 mm behind the limbus, and the central 2 5 mm deepened to expose the ciliary body (Fig. la). To obtain a circular opening into the vitreous cavity a Address for reprints: P. K. Leaver, FRCS, Moorfields Eye Hospital, City Road, London ECIV 2PD
